When we think of user experience (UX) or user interface (UI) design, chances are we picture a beautiful interface – sleek layouts, vibrant colors, and maybe even a futuristic touch. Visual appeal is undeniably important, as a polished look can grab attention immediately. In fact, users form opinions about a website’s design within mere milliseconds, which means first impressions online are almost instant, and that is why many designers prioritize aesthetics, hoping to make users go “wow” at first glance.
First Impressions in Visual Design
A visually clean, modern interface can instantly convey professionalism and draw users in. First impressions are overwhelmingly influenced by a site’s visual design, even more so than its usability. In other words, we naturally gravitate toward designs that are easy on the eyes and inviting.
We’re all guilty of sometimes “judging a book by its cover”. Online, this translates to judging an app or website by its look and feel. Research has found it takes only about 50 milliseconds (0.05 seconds) for users to form an opinion about a website, which essentially is a snap judgment of its credibility or attractiveness. In those first moments, the design appears to play a huge role in whether people stick around or hit the back button. Visual appeal often takes center stage in UX discussions because it’s the most immediate, visceral aspect of an experience.

This research, “What is beautiful is usable. Interacting with Computers,” concludes that visually appealing websites are perceived to be more usable, thus, making a vibrant color scheme, crisp typography, and modern layouts proportionally signaling professionalism and delight to set a positive tone from the start.
This emphasis on aesthetics is very much evident in real-world examples. In early 2024, the new productivity app Amie generated massive buzz because of its homepage in which, as users scroll, they transition into an interactive landing page. It was a unique, eye-catching design and smooth UI. The app took X (formerly Twitter) by storm, gaining thousands of excited users at launch. It was even reviewed by Marques Brownlee (MKBHD) on his Waveform podcast, who highlighted Amie’s sleek look in his content. The immediate “wow” factor of Amie’s interface got people talking and downloading, which is evidence that visual appeal alone can create powerful first impressions that can draw people to take some sort of action.
First impressions, apart from visual appeal, can depend heavily on cultural context. The color white is associated with purity in Western cultures but connotes mourning in parts of Asia, and a lucky red in China might imply danger elsewhere. Moreover, a design that works beautifully for a domestic audience “may not make any sense to people from a different cultural background,” as one UX researcher put it. And, in addition to Snap Judgments influencing immediate reactions, research shows it also affects the quality of a website’s design directly affects whether users trust the brand, and even their likelihood to purchase). So the way to nail that first impression is about conveying credibility and compatibility with the audience’s expectations from the very first glance as much as it is about wow-ing the users.
Why Looks Aren’t Everything
That said, a dazzling first impression can be fleeting if it is not backed by substance, similar to how many users that tried Amie were initially wowed by the interface, but soon after launch, the app’s sudden popularity overwhelmed its servers, as said by the CEO a month ago, and for days, many couldn’t even use the service. But more than that, users reported limited features and missing integrations that made the tool less-usable in real workflows, making it to be just another calendar app behind this great-looking landing page.
An application or site can be gorgeous, but if it’s slow, confusing, or unreliable, users won’t stick around. They likely wouldn’t even return to the homepage. As impressive as it may be for a first impression, it’s the antithesis of a sustainable, recurring experience. Amie focused solely on aesthetics. The marketing was right and won the initial admiration, but the product wasn’t as fit for the market.
A known phenomenon in UX called the aesthetic-usability effect suggests that an attractive design can temporarily mask usability issues. Users who encounter problems might still rate the product highly at first because it looks good, with the visual appeal giving a positive emotional bias. However, that doesn’t mean those problems go away, it just means people might not notice them immediately.

Eventually, if navigation is unintuitive or features don’t meet needs, the initial goodwill fades like it did for Amie. And as UXers often note, no matter how tiresome it is to hear, visual design should never come at the expense of the basics. Thus, no amount of pretty visuals can save a product that frustrates its users in practice.
What does this mean for designers and product teams? It is simply to not neglect core usability, performance, and the nuanced, unique selling point that users yearn for, which is—as Mr Beast would say—is to ‘confirm the thumb’, and that is—in our context—to deliver an experience that lives up to the story your marketing so boldly tells. Focusing on meaningful fundamentals, clear navigation, responsiveness, and accessible content are just as critical as the visuals. Yes, users love a gorgeous interface, but they also need one that makes sense and is reliable. The best products achieve a balance that wows on the surface and works beautifully underneath.
Focusing on beauty alone can backfire once users start clicking around, and there is no better example than the classic real-world case between MySpace and Facebook. MySpace allowed flashy, personalized profile pages with custom layouts, which actually led to the site being confusing and slow. Every page looked very different from the other, often cluttered with music and videos that bogged down the experience.
Facebook, by contrast, kept profiles clean and consistent which proved to be far more usable, although ironically, today it’s more cluttered. But back then with a very slow internet speed, users overwhelmingly preferred Facebook’s stability and simplicity, underscoring that flashy design alone can’t make up for poor UX. Even outside of social media, the same principle holds. If a site is visually stunning but frustrating to use, people won’t stick around. 42% of visitors will abandon a website due to poor functionality or confusing navigation no matter how nice it looks. Completely on the other side is a site like Craigslist, which looks straight out of the 90s but remains hugely popular, and as of March 2025 according to SimilarWeb, garners over 125 million monthly users.
Designing for the Human Mind
Every click, hover, and interaction a user has with a design is influenced by how their mind processes information, and the way to do so and how most effective interfaces are built, is by understanding the science behind cognitive science and human behavior. The best designers draw on research into how people think, learn, and decide, using the principles of cognitive psychology. Understanding how users perceive, remember, and process information in context is essential for designers to attempt to match those expectations and even guide behaviors in subtle ways.

The reason why a good app seems to “just know” what we want to do next often comes from applying psychological insights. Consistent layouts and familiar icons are placed in specific ways to ensure alignment with users’ mental models so that they don’t have to re-learn basic tasks in each app they use. Familiarity is important, and so is minimizing cognitive load by breaking complex tasks into steps or grouping related items, as our brains can only handle so much at once.
Equally important is effective copywriting that reflects how we naturally read and interpret, and visual hierarchy that guides our attention and leads our eye to the most important elements are some of the ways to help mitigate potential user dropoff. Therefore, it is essential to ensure that a product looks appealing; as we discussed, first impressions matter, but it is also as essential to sustain that ‘wow’ sensation to meet the expectations by aligning with natural human behavior. Making the experience that ‘just feels right’ allows users to navigate effortlessly, understand information quickly, and achieve their goals with minimal frustration.
As great UX design aligns with how our minds naturally work, relying on cognitive principles first is a great start to make interactions feel effortless. We take an example of Fitts’s Law, which predicts that the time needed to click a target depends on the target’s size and distance, which in plain terms means closer, larger buttons are faster and easier to hit. The big tappable buy buttons we usually see, along with the most important buttons that stick to the screen edges can be attributed to Fitt’s Law. It draws our eyes and our cursor can acquire them with less effort. Similarly, Hick’s Law reminds us that the more options we dump on a user at once, the longer it takes for them to decide. Supermarket is a classic example of how too much choice can even trigger decision paralysis or fatigue.
One of the most important purposes of a very good user interface is to fight this overload by streamlining choices by using various techniques like progressive disclosure, sensible defaults, or bite-sized steps, so the user’s brain doesn’t overheat from weighing twenty things when all they wanted was one. And like Don Norman often says, designing for how humans feel along with how we think is the notion we should not ignore. He notes that people experience products on three levels: the visceral, the behavioral, and the reflective.
Don explains that the visceral level is our gut reaction – that instant “ooh, this looks nice” (or “yikes!”) when we first see an interface. The behavioral level is about usability in action: how pleasurable and easy the product is to actually use day-to-day. Finally, the reflective level kicks in when we step back and consider what the experience means to us – does it align with our values, do we feel smarter or happier having used it? Therefore, it is essential that UX speak to the user’s goals as well as speak to the human mind and heart so that the product becomes as spontaneous and thinking.
Key Takeaways
- First Impressions Matter: Users form an opinion about a product’s design within milliseconds, so visual appeal does have a significant impact on initial perception that can draw users in and signal credibility.
- Aesthetics vs. Usability: However, focusing on looks alone with the product does not validate the promise is a mistake. A pretty-looking UI can masquerade usability issues of a product for a short time, but what it cannot do is keep them for long enough for the business to sustain itself.
- Balance is Key: An app or site should always attempt to combine visual polish with solid, nuanced UX functionality that does not neglect basics like navigation, speed, and accessibility; instead, works hand-in-hand with aesthetics to deliver an exceptional experience.
- Don’t Ignore Science: And, as the title of this article suggests, we should ‘Design Smarter, and then Prettier.’ Design ought to be grounded in how humans think and behave, and therefore, applying cognitive science principles should be a no-brainer to make the design thoughtful and enduring.
